Much has been written about the soy and breast cancer relationship. Initial interest in this relationship focused on the role that soy isoflavones may have in reducing the risk of developing breast cancer.1,2 But in the late 1990s, rodent research raised the possibility that soyfoods might worsen the prognosis of women with this disease.3 It […]
Epidemiologic studies are not designed to establish cause and effect relationships because it is not possible to control for all potentially confounding variables. Additionally, it is difficult to accurately assess dietary intake. Nevertheless, epidemiologic studies have played an important role in informing dietary guidelines. Although intervention studies carry the most weight within the scientific community, […]
In 1995, Lamartiniere et al.1,2 proposed that the isoflavone genistein when consumed early in life reduces risk of developing breast cancer later in life. Over the past nearly 30 years, both animal3 and epidemiologic evidence4-7 has accumulated in support of this proposal. Nevertheless, the hypothesis that consuming isoflavone-rich soy during childhood and/or adolescence reduces breast […]
Modern research interest in soyfoods began with a focus on cancer prevention and treatment.1 Much of this interest can be attributed to the soybean being a uniquely rich source of isoflavones, and in particular, genistein. New pre-clinical research by Sharma et al.2 suggests that genistein may have a role in the prevention and treatment of […]
Beginning in the late 1990s, concerns arose that soy increases breast cancer risk and worsens the prognosis of women with this disease despite the historically low breast cancer incidence rates in soyfood-consuming countries.1 However, observational data published beginning in 2009,2 showed just the opposite, post-diagnosis soy intake was associated with reduced mortality and recurrence.3 A […]
The European Union’s Assessment Group on Glyphosate (AGG) recently released an 11,000-page draft report concluding that glyphosate, the world’s most widely used herbicide, does not warrant being declared carcinogenic (see exact wording below).1 If adopted by the AGG, it will add to the long list of health agencies that have declared the world’s most widely […]
The historically low incidence rates of breast cancer in soyfood-consuming countries led to initial enthusiasm that soy intake could reduce risk of developing this disease. While appropriate as a basis for speculation, considerably more informative are breast cancer rates among Asian women who regularly consume soy in comparison to those who do not. Such comparisons […]
The health effects of cow’s milk have been hotly debated over the past couple of decades. Two recent publications call into question current dietary milk recommendations,1,2 one of which also highlights the benefits of replacing cow’s milk with soymilk in relation to breast cancer risk.2 In a review on milk and health published in the […]
Excitement about the possibility that soyfoods reduce risk of developing breast cancer began in earnest 30 years ago. While over this time support for a protective effect has waxed and waned, there has been a constant struggle to identify a mechanism by which soy could exert its proposed protective effect. It isn’t necessary to know […]
Expert notes soy doesn’t increase risk of cervical cancer but fails to highlight that it may be proactive against this disease. A woman who frequently consumed soy was diagnosed with cervical cancer. Upon hearing the news, the woman’s mother said she knew the reason. “All the soy” in her diet “was the leading cause of […]
